I guess so... I haven't quite figured out if all of "Merge" and "Match" should be all combined together or not yet.

In Rhino just from the way things pieced together, there is a MergeEdge and MergeSrf, but no plain "Merge" for curves... Then separately there is Match for curves, and MatchSrf for surfaces.

It might make sense in MoI to have this boil down to 2 different commands - Merge that works on curves (no continuity options, just makes it one fully smooth segment), edges that are tangent, and surfaces, and then a Match (with continuity options here) that works on curves and surfaces for editing their shape but keeping them separate objects...

If it is all combined into one single command, it will be difficult to label the MatchSrf functionality because editing a surface to make it smooth to another one does not really fit so great with the term "Merge".
